Disclosed are methods and systems that enable real-time, continuous reduction in the rate of degradation of oils used to fry foods. The disclosed methods and systems accomplish this by reducing the rate of accumulation of undesirable oil breakdown byproducts, keeping the levels of these undesirable compounds below those at which food quality is negatively impacted and oil degradation accelerates. The disclosed methods and systems thus enable improved frying oil lifetimes, decreased frying oil consumption, greater consistency in fried food quality, and/or improvements in worker safety relative to conventional frying methods.

The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using said compositions. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition.

The present technology provides a method that includes contacting a composition with a caustic solution to produce a caustic-treated composition; combining the caustic-treated composition with silica particles to produce a slurry; and removing the silica particles from the slurry to produce a treated composition; wherein the composition includes one or more of animal fats, animal oils, plant fats, plant oils, vegetable fats, vegetable oils, greases, and used cooking oil and the composition includes: at least about 10 wppm of total metals, at least about 8 wppm of phosphorus, at least about 10 wppm of chlorine, at least about 10 wppm of sulfur, at least about 20 wppm of nitrogen, at least about 5 wt. % of free fatty acids; and has an acid number from about 10 mg KOH/g to about 150 mg KOH/g, and the silica particles has a particle size from about 10 microns to about 50 microns, a BET surface area from about 200 m.sup.2/g to about 1000 m.sup.2/g.

The present invention relates to a method of filtering an oil, the method including the following steps (A) and (B): (A) allowing a hydrophobic gas to permeate through a porous membrane including a hydrophobic polymer as a main component; and (B) allowing an oil to permeate through the porous membrane, in which the step (B) is performed after the hydrophobic gas that has permeated through the porous membrane is confirmed to have a relative humidity of 0 to 60% in the step (A).

The present disclosure is generally directed to methods for purifying cannabinoids from Cannabis plants.

A system for treating whole stillage includes a stillage tank, a separation system in communication with the stillage tank and configured to separate the whole stillage into a wet cake portion and a thin stillage portion, and a primary filtration system in communication with the separation system. The primary filtration system can be configured to separate the thin stillage into a primary concentrate and a primary permeate. A secondary filtration system in communication with the primary filtration system can be configured to further purify the primary permeate. A water reclamation system in communication with the primary and/or secondary filtration system can remove water from the permeate. An additive can be added to the primary permeate to precipitate phosphorus-containing minerals and corn oil can be advantageously extracted from the primary concentrate. Protein-enriched animal feeds can be generated from dehydration of the primary concentrate.

Remediating hemp oil includes controlling heat and oxygenation levels to reduce the relative weight percentage of THC while mitigating the conversion of other cannabinoids to other compounds. The method may include bubbling air, oxygen, or another oxygen-containing gas into a reactor while maintaining the temperature of the hemp oil.

There is a method for extracting bio-oil from algal biomass, in particular oily microalgae, using solvents of a Deep Eutectic Solvents (DES) capable of producing a bio-oil with a low content of phospholipids and inorganic salts, mainly sodium chloride.

A characteristic of edible oil used for frying operations may be determined using a sensor such as a spectrometer or capacitive sensor. Other attributes indicative of a prior, present, or future frying operations can be specified, and an analytical model indicative of a composite aging parameter can be applied using one or more attributes along with data obtained from the sensor indicative of oil degradation. Application of the analytical model may be used to trigger various actions relating to oil management, such as ranging from automatically generating a notification to an operator or automatically initiating oil management operations such as top-off, oil removal, or oil replacement in a frying apparatus.

Disclosed is a method of preparing krill oil. A method of preparing krill oil may include providing a dried krill powder; obtaining an extract after adding spirits of wine to the dried krill powder; obtaining a passing solution from which salt and cholesterol are removed by passing the extract through a column; obtaining a krill concentrate by decompression-concentrating the passing solution; and obtaining krill oil by stationarily positioning a mixture obtained by adding spirits of wine to the krill concentrate, layer-separating the stationarily positioned mixture, extracting a supernatant of the layer-separated mixture, and concentrating the extracted supernatant.
